282# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
283# $ac_aux_dir to '$srcdir/foo'.  In other projects, it is set to
284# '$srcdir', '$srcdir/..', or '$srcdir/../..'.
285#
286# Of course, Automake must honor this variable whenever it calls a
287# tool from the auxiliary directory.  The problem is that $srcdir (and
288# therefore $ac_aux_dir as well) can be either absolute or relative,
289# depending on how configure is run.  This is pretty annoying, since
290# it makes $ac_aux_dir quite unusable in subdirectories: in the top
291# source directory, any form will work fine, but in subdirectories a
292# relative path needs to be adjusted first.
293#
294# $ac_aux_dir/missing
295#    fails when called from a subdirectory if $ac_aux_dir is relative
296# $top_srcdir/$ac_aux_dir/missing
297#    fails if $ac_aux_dir is absolute,
298#    fails when called from a subdirectory in a VPATH build with
299#          a relative $ac_aux_dir
300#
301# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
302# are both prefixed by $srcdir.  In an in-source build this is usually
303# harmless because $srcdir is '.', but things will broke when you
304# start a VPATH build or use an absolute $srcdir.
305#
306# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
307# iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
308#   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
309# and then we would define $MISSING as
310#   MISSING="\${SHELL} $am_aux_dir/missing"
311# This will work as long as MISSING is not called from configure, because
312# unfortunately $(top_srcdir) has no meaning in configure.
313# However there are other variables, like CC, which are often used in
314# configure, and could therefore not use this "fixed" $ac_aux_dir.
315#
316# Another solution, used here, is to always expand $ac_aux_dir to an
317# absolute PATH.  The drawback is that using absolute paths prevent a
318# configured tree to be moved without reconfiguration.
